Apparatus for improving flow between intersecting passageways

Abstract

A member has a first surface and a second surface. The first surface defines a first passageway, and the second surface defines a second passageway that intersects the first passageway at a first opening. An insert is at least partially disposed within the second passageway and extends into the first passageway. The insert defines a third passageway having a second opening that is within the first passageway.

1 . An apparatus comprising:
 a member having a first surface and a second surface;   said first surface defining a first passageway, and said second surface defining a second passageway that intersects the first passageway at a first opening; and   an insert being at least partially disposed within the second passageway and having an end that extends into the first passageway;   wherein the insert defines a third surface that defines a third passageway having a second opening at the end in the first passageway.   
     
     
         2 . The apparatus of  claim 1 , wherein the third passageway is at least partially coextensive with the second passageway. 
     
     
         3 . The apparatus of  claim 1 , wherein the third passageway is tapered adjacent the second opening. 
     
     
         4 . The apparatus of  claim 1 , wherein the insert includes a contoured surface that cooperates with a region of the second surface adjacent the first opening to form a concavity. 
     
     
         5 . The apparatus of  claim 1 , wherein the insert includes a portion that bisects the second opening. 
     
     
         6 . The apparatus of  claim 1 , wherein one side of the insert extends further into the first passageway than the other side of the insert, thereby to form a scoop portion. 
     
     
         7 . The apparatus of  claim 1 , wherein all the surfaces of the insert that are disposed within the first passageway are contoured. 
     
     
         8 . The apparatus of  claim 1 , wherein the member defines a first stop surface;
 wherein the insert defines a second stop surface; and   wherein the first stop surface contacts the second stop surface and thereby limits movement of the insert into the first passageway.   
     
     
         9 . An apparatus comprising:
 a member having a first surface that defines a first passageway, and a second surface that defines a second passageway intersecting the first passageway at a first opening; and   an insert that is at least partially disposed within the second passageway and that has an end that extends into the first passageway;   wherein the end of the insert that extends into the first passageway includes at least one contoured surface.   
     
     
         10 . The apparatus of  claim 9 , wherein the insert defines a third passageway having a second opening in the end of the insert that extends into the first passageway; and
 wherein said at least one contoured surface defines a tapered portion of the third passageway.   
     
     
         11 . The apparatus of  claim 9 , wherein the second surface includes a region adjacent to the first opening; and
 wherein said at least one contoured surface includes a contoured surface that cooperates with the region of the second surface adjacent to the first opening to define a concavity.
